Inventor f07z7z 16222 verzf flllorney Patented Jan. 3, 1933 PAT tFlCEJOHN F. CALVERT, OF HUNTINGTON, INDIANA CASEMENT WINDOVJ HOLDERApplication filed May 9,

This invention relates to improvements in casement window constructionand more particularly to a novel fastening means whereby the casementwindow can be retained in any predetermined inclined position.

The principal objectof this invention is to provide an easily operatedretaining means whereby a casement window can be set at anypredetermined inclined open position.

The following is a brief description of the figures of the drawings.

Figure 1 represents a fragmentary vertical sectional View of thecasement window in closed position.

Fig. 2 represents a vertical fragmentary sectional view on the casementwindow in open position. J

Fig. 3 represents a fragmentary detailed sectional view of the fasteningmeans.

Fig. 4 represents a fragmentary side elevational view of the fasteningmeans shown in Fig. 8.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that numeral 5 represents the side of the window frameconstruction to which the casement window 6 is hingedly connected as at7 The casement window 6 abuts, when in closed position the sill 8 towhich the retaining means generally referred to by numeral 9 is secured.

Numeral 10 represents an elongated arcuate and substantiallysemi-circular shaped bar provided at equal spaced intervals withJ-shaped notches 11. One end of this bar 10 is pivotally connected as at12 to an ear 40 13 on the casement window 6, while the opposite endportion is provided with some form of stop means 14. This bar 10 isslidable through the fastening or retaining means 9, and as is clearlyshown in Figs. 3 and 1-, 45 this retaining or fastening means consistsof a base plate 15 having outstanding end members 16 against which restthe end portions of the outer plate 17.

The base plate 15 and the plate 17 are provided with opposed recesses18, which form 1931. Serial No. 610,173.

a guideway for the block 25. Numeral 19 represents a pin disposedthrough the plates 15 and 17, the same having swingably disposedthereon, the dog 20. This dog 20 is provided with a handle shank 21.

Numeral 22 represents the enlarged fulcrum portion of the dog 20, thesame being provided with a notch 23 into which bears the leaf spring 24,said spring being adapted I to maintain the block 2 1 in bar engaged po-0 sition. The aforementioned block 25 has a cavity 26 therein, withinwhich engages the dog 20. This block 25 bears against the smooth edge ofthe bar 10, while the notched edge portion of the bar rides against thepin 27 which is disposed transversely between the plates 15 and 17.

It can now be seen, that normally, with the dog 20 in the position shownclearly in Fig. 3, tension will be exerted against the bar 10 formaintaining the bar engaged against the pin 27 so that the pin 27 willbe engaged snugly within a particular notch 11, depending upon theposition at which 7 the operator wishes to set the easement window.

The operator determines this by engaging or disengaging the block 25 bythe handle 21 and moving the window 6. lVhen moved upwardly the block 25exerts a wedging action against the bar 10 for urging the same againstthe pin 27.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is 1. Retainingmeans for closures comprising a bar, said bar being provided withnotches in one side thereof, a stationary member against which the barcan engage at its notched side, a slidable wedge member for exertingpressure against the bar when moved in a given direction, means foractuating the wedge member, said wedge member being provided with arecess, a swingable dog engaged in the recess, and a handle formanipulating the dog to actuate the wedge member.

2. Retaining means for closures comprising a bar, said bar beingprovided With notches in one side thereof, a stationary member againstwhich the bar can engage :at its notched side, a slidable Wedge memberfor exerting pressure against the bar when moved in a given direction,means for actuating the Wedge member, said Wedge member being providedwith a recess, a swingabie dog engaged in the recess, a handle formanipulating the dog to actuate the Wedge member, and a spring engagedagainst the dog for retaining the dog in a position maintaining theWedge member against the bar.

In testimony whereof I affix my signature.

JOHN F. CALVERT.
